SOFAArk 容器提供了一个简单的 telnet 服务端小工具，用于运行时查看容器状态，目前支持查看 Plugin 和 Biz 相关信息。

使用方式

使用 telnet 连接服务端，端口号为 1234，例如：

telnet localhost 1234

进入交互界面:

➜ telnet localhost 1234
Trying 127.0.0.1...
Connected to localhost.
Escape character is '^]'.

其他命令可以查看提示信息，暂时不支持 -s 选项查看服务。

Biz 命令

biz 命令支持查看 biz 相关信息，也支持安装、卸载、激活等 biz 操作指令。例如

sofa-ark>biz -m mvc-two:0.0.1-SNAPSHOT
BizName:                  mvc-two
Version:                  0.0.1-SNAPSHOT
Priority:                 100
MainClass:                com.example.mvctwo.MvcTwoApplication
WebContextPath:           another
Deny Import Packages:     \
Deny Import Classes:      \
Deny Import Resources:    \

其他命令可以查看提示信息，暂时不支持 -s 选项查看服务。需要注意的是，Telnet 服务端只是 SOFAArk 提供的方便运行时查看信息工具，不推荐直接通过 telnet 指令在线上执行 Biz 操作指令，推荐使用 API 或者动态配置方式。
